Hi,
Actually, i am using this java code below :
try {
    //     create XML structure of mail package
    String output = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"
           + "<ns:Mail xmlns:ns=\"http://sap.com/xi/XI/Mail/30\">"         
           + "<Subject>" + mailSubject     + "</Subject>"
           + "<From>" + mailSender     + "</From>"
           + "<To>" + mailReceiver     + "</To>"
           + "<Content_Type>multipart/mixed; boundary=\"" + boundary + "\"</Content_Type>"
           + "<Content>";
    out.write(output.getBytes());
    // create the declaration of the MIME parts
    //First part
    output = "--" + boundary + CRLF
           + "Content-Type: text/plain; charset=UTF-8" + CRLF
           //+ "Content-Transfer-Encoding: 8bit" + CRLF
           + "Content-Disposition: inline" + CRLF + CRLF
           + mailContent + CRLF
    //Second part
    + "--" + boundary + CRLF
    + "Content-Type: Application/pdf; name=" + attachmentName + CRLF  
    //+ "Content-Transfer-Encoding: base64" + CRLF
    + "Content-Disposition: attachment; filename=" + attachmentName + CRLF + CRLF;
    out.write(output.getBytes());
    //Source is taken as attachment
    copySource(in, out);
    out.write("</Content></ns:Mail>".getBytes());
  } catch (IOException e) {
    throw new StreamTransformationException(e.getMessage());
protected static void copySource(InputStream in, OutputStream out)
     throws IOException {
    byte[] bbuf = new byte[in.available()];
    int bblen = in.read(bbuf);
    if (!(bblen < 0)) {
      //String sbuf = new String(bbuf);
      //String encoded = Base64.encode(sbuf);
      // replace all control characters with escape sequences
      //sbuf = sbuf.replaceAll("&", "&amp;");
      //sbuf = sbuf.replaceAll("\"", "&quot;");
      //sbuf = sbuf.replaceAll("'", "&apos;");
      //sbuf = sbuf.replaceAll("<", "&lt;");
      //sbuf = sbuf.replaceAll(">", "&gt;");
      out.write(bbuf);
This code working fine with text file but not for pdf file. because i got error in mail adapter :
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: com.sap.aii.messaging.util.XMLScanException: java.lang.NullPointerException; nested exception caused by: com.sap.engine.lib.xml.parser.NestedSAXParserException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException: Unsupported character: 8f(:main:, row:11, col:4)(:main:, row=11, col=4) -> com.sap.engine.lib.xml.parser.ParserException: Unsupported character: 8f(:main:, row:11, col:4)
I guest the problem because the mail adapter doen't accept pdf content insite the mail package.
please advise me
Best Regards
Fernand
